and clock channels. These channels are used to carry video, audio, and auxiliary data.
In addition, HDMI carries a VESA DDC. The DDC is used by an HDMI Source to
determine the capabilities and characteristics of the sink.

Audio, video, and auxiliary (control/status) data is transmitted across the three TMDS
data channels. The video pixel clock is transmitted on the TMDS clock channel and is
used by the receiver for data recovery on the three data channels. The digital display
data signals driven natively through the processor are AC coupled and needs level
shifting to convert the AC coupled signals to the HDMI compliant digital signals.

Stereoscopic Support on HDMI
The processor display supports HDMI 1.4 3D video formats. If the HDMI panel is
detected to support 3D video format, then the software driver will program Pipe2dB for
the correct pipe timing parameters.

The left and right frames can be loaded from independent frame buffers in the main
memory. Depending on the input S3D format, the display controller can be enabled do
perform frame repositioning, image scaling, line interleaving.

Digital Video Interface (DVI)
The Digital Ports can be configured to drive DVI-D. DVI uses TMDS for transmitting
data from the transmitter to the receiver which is similar to the HDMI protocol but
without the audio and CEC. Refer to the HDMI section for more information on the
signals and data transmission. To drive DVI-I through the back panel the VGA DDC
signals are connected along with the digital data and clock signals from one of the
Digital Ports. When a system has support for a DVI-I port, then either VGA or the DVI-
D through a single DVI-I connector can be driven but not both simultaneously.
